This is a remote position.
You’ll build and scale the iOS experiences that power patient and provider journeys—from onboarding and scheduling to remote monitoring and care delivery. You’ll work closely with product, design, backend, and QA to ship crisp, reliable features that plug into our FHIR-based backend, integrate with Apple Health (HealthKit), and connect to real-world devices over Bluetooth (BLE) and broader IoT workflows. You’ll also help drive acquisition and activation by wiring up deep links and ad attribution tooling. As you ship, you’ll raise the bar on performance, reliability, and the day-to-day engineering practices that keep a fast-moving team shipping confidently.
Build iOS features end-to-end: discovery, technical design, implementation, rollout, and iteration.
Develop and maintain a modern iOS codebase using Swift and SwiftUI (with UIKit where appropriate).
Integrate with backend services, including FHIR APIs (e.g., Patient, Appointment, Encounter, Observation, Medication, etc.), ensuring robust networking, error handling, and resiliency.
Build remote health monitoring experiences and data flows (device pairing, background sync, data integrity, user consent, and UX for connection states).
Integrate Bluetooth Low Energy (BLE) devices: scanning, pairing, GATT services/characteristics, permissions, reconnection strategies, and battery/performance considerations.
Implement Apple Health integration using HealthKit (reading/writing supported data types, authorization flows, background delivery where applicable, and privacy-safe handling).
Implement deep linking (Universal Links and/or custom URL schemes), including routing, deferred deep links, and robust analytics tracking.
Integrate mobile attribution tools (e.g., AppsFlyer or similar) and ensure accurate event tracking across install → activation → conversion funnels.
Embed security into development: secure storage, encryption where appropriate, privacy-by-design, audit-friendly logging patterns, and safe handling of sensitive health data.
Improve app performance and production reliability (crash analysis, profiling with Instruments, monitoring, root-cause fixes).
Contribute to engineering standards: code quality, testing strategy, architecture patterns, and API conventions.
Build and maintain automated tests (unit/integration/UI) and improve legacy areas safely.
Collaborate cross-functionally to translate product requirements into scalable technical solutions and high-quality UX.
Create and maintain technical documentation (architecture notes, runbooks, release checklists).
3+ years building production iOS applications and shipping features end-to-end.
Strong proficiency in Swift and experience building with SwiftUI (and UIKit as needed).
Solid understanding of iOS fundamentals: app lifecycle, memory management, performance, concurrency.
Strong networking experience (REST/JSON) and comfort building resilient API integrations (pagination, retries, caching).
Hands-on experience with BLE development on iOS (CoreBluetooth), including handling unreliable connectivity and real-world device behaviors.
Experience with HealthKit / Apple Health integrations (permissions, background behavior, privacy considerations).
Experience implementing deep links (Universal Links) and in-app routing/navigation patterns.
Familiarity with mobile analytics and ad attribution SDKs (AppsFlyer, Adjust, Branch, Firebase, etc.) and event instrumentation.
Strong testing mindset (XCTest; unit/UI testing practices).
Experience debugging production issues and working with crash reporting tools.
Strong communication skills and ability to work effectively in a remote, cross-functional team.
Familiarity with healthcare interoperability standards, especially FHIR (and/or SMART on FHIR).
Experience with background execution constraints (BLE reconnect, HealthKit delivery, background tasks) and strategies for reliable sync.
Experience with device/IoT ecosystems (firmware quirks, calibration, data validation, and support tooling).
CI/CD tooling for iOS (Fastlane, GitHub Actions, Bitrise, Xcode Cloud, etc.).
Observability/analytics instrumentation, feature flags, and experimentation (A/B testing).
Experience building apps that handle sensitive data (privacy and compliance-oriented practices).
